Plus de Wifi après upgrade vers Xubuntu 18.04 (RTL8723BE) - [Résolu]
Bonjour,
J'ai un PC portable PackardBell qui fonctionnait à merveille sous Xubuntu 16.04 LTS.
J'ai fait un upgrade pour passer à Xubuntu 18.04 hier, tout semble s'être bien passé, mais.... plus de connexion Wifi.
Le système semble s'authentifier correctement puis se déconnecte au bout de 46 secondes.
Je vois un peu partout que plein de gens ont eu le même problème que moi, les solutions proposées sont diverses et variées, je ne sais pas quoi faire, sachant que je veux éviter une réinstallation.
Pourriez-vous SVP m'indiquer la bonne démarche ?
Merci d'avance.
Voici ce que je constate dans la trace "dmesg" :

Re : Plus de Wifi après upgrade vers Xubuntu 18.04 (RTL8723BE) - [Résolu]
Bonjour,
Montre :
bootctlVérifie le réglage d'antenne > [Résolu]Pas de connexion wifi RTL8723BE Livebox et Ubuntu 16.04.
Tente :
echo blacklist acer-wmi | sudo tee -a /etc/modprobe.d/blacklist-acer-wmi.confSuivi d'un redémarrage du système.
La Doc > acer_wmi permettant de blacklister le module WLAN.
Voir le § 6-C > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier

Re : Plus de Wifi après upgrade vers Xubuntu 18.04 (RTL8723BE) - [Résolu]
Bonjour,
Merci pour ta réponse rapide. J'ai toujours le problème, malgré les actions suivantes :
- essai de réglages des antennes : niveau de signal identique pour les deux donc je n'ai pas fait de modif (cf trace plus bas)
- blacklistage des modules acer-wmi et ideapad_laptop puis redémarrage :
dom@Packard-ENLG71BM:~$ cat /etc/modprobe.d/blacklist-acer-wmi.conf
# ajout pour essayer de faire marcher le wifi, suite upgrade vers 18.04
blacklist acer-wmi
dom@Packard-ENLG71BM:~$
dom@Packard-ENLG71BM:~$ cat /etc/modprobe.d/blacklist-ideapad.conf
# ajout pour regler pb de wifi suite upgrade 18.04
blacklist ideapad_laptopvoici le résultat de bootctl et autres commandes utiles (j'ai refait un wificheck)

Bonjour,
dom.reboud a écrit :
J'ai un PC portable PackardBell qui fonctionnait à merveille sous Xubuntu 16.04 LTS.
J'ai fait un upgrade pour passer à Xubuntu 18.04 hier, tout semble s'être bien passé, mais.... plus de connexion Wifi.
On a vu ce problème parfois lors de mises à niveau 16.04 -> 18.04.
Serait bon de voir le contenu du fichier /etc/NetworkManager/NetworkManager.conf:
cat /etc/NetworkManager/NetworkManager.confA+

Re,
Fausse piste concernant NetworkManager.conf, le contenu semble correct.
Il manque le « up » à la fin de la commande suggérée par @xubu1957 au #8:
sudo ip link set wlp2s0 upA+

Re : Plus de Wifi après upgrade vers Xubuntu 18.04 (RTL8723BE) - [Résolu]
Bonjour,
@xubu, ylag et Naziel : il faut cloner le dépôt de L. Finger et installer avec dkms. Le driver qui vient avec le noyau 4.15 ne fonctionne pas avec le 8723be. J'ai eu le problème, il se charge mais ne se connecte jamais à la box.
sudo apt install --reinstall build-essential dkms git
cd
rm -rfv rtlwifi_new
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
source dkms.conf
sudo mkdir /usr/src/$PACKAGE_NAME-$PACKAGE_VERSION
sudo cp -r * /usr/src/$PACKAGE_NAME-$PACKAGE_VERSION
sudo dkms add $PACKAGE_NAME/$PACKAGE_VERSION
sudo dkms autoinstall $PACKAGE_NAME/$PACKAGE_VERSIONEDIT : je n'avais pas vu l'intervention d'ylag.

Re : Plus de Wifi après upgrade vers Xubuntu 18.04 (RTL8723BE) - [Résolu]
Bonjour,
La mise en place du driver de L. Finger n'a pas fonctionné, la compilation se plante.
En cherchant d'autres pistes, je suis tombé sur ce sujet
La solution 1 conseille tout bêtement un upgrade de la distribution.
Comme je n'avais pas grand chose à perdre, j'ai lancé un upgrade vers Xubuntu 19.10.
Tout s'est bien passé, et le Wifi fonctionne, donc mon problème est résolu.
Merci à tous pour votre aide.
Je poste les traces de l'installation du driver qui ne fonctionne pas :

Re : Plus de Wifi après upgrade vers Xubuntu 18.04 (RTL8723BE) - [Résolu]
Bonjour,
dom.reboud, au #14 a écrit :
En cherchant d'autres pistes, je suis tombé sur ce sujet
La solution 1 conseille tout bêtement un upgrade de la distribution.
Ce que @lobo1512 suggérait dans 1ere solution proposé : update/upgrade n'était pas une migration (mise à niveau) vers une autre distribution, mais simplement de passer les mises à jour sur la distribution existante...
Maintenant, tant mieux si ça fonctionne par défaut sur la 19.10 ! 
A+

La mise en place du driver de L. Finger n'a pas fonctionné, la compilation se plante.
Bonsoir,
Effectivement, elle ne passe pas sur un 4.15. Par contre le commit du 5 mars si...
Un simple git checkout 9dd7de8bcd53f3de55363cf76b8c92329c2e8e8b permettait de compiler et probablement de résoudre ton problème...
Tu es passé sur une 19.10, dont la maintenance se termine en juillet 2020, contre avril 2023 pour la 18.04

Bonjour,
Effectivement, la version 19.10 sera bientot périmée, il faudra que je passe prochainement vers la 20.04 LTS.
Merci pour votre aide.
